The performance of resistance exercises on unstable equipment has increased in popularity, despite the lack of research supporting their effectiveness. Resistance exercise performed on unstable equipment may not be effective in developing the type of balance, proprioception, and core stability required for successful sports performance. Free weight exercises performed while standing on a stable surface have been proven most effective for enhancing sports related skills.

Jeffrey M. Willardson is currently completing doctoral studies in exercise and wellness with a concentration in resistance exercise prescription at Arizona State University.
